I have an early-nineties GT mountain bike with a titanium fre. It's still a good-looking, lightweight bike, but its rear U-brake has no real power. Are there any compatible brakes with better grip, or are there any pads with magical powers? Andreas Reno, Nevada

I've read your praise for the Yashica T4 point-and-shoot camera and was attempting to locate a refurbished unit on the web, when, lo and behold, up pops the new Yashica T4 Zoom with a Carl Zeiss Lens (28mm to 70mm). In the wilderness, I've always managed to catch more pictures than fish, and would appreciate your thoughts on a lightweight point-and-shoot for my arduous outdoor adventures. Scott Maple Valley, Washington

Why did Sno-Seal fall out of favor? I kept a pair of heavy hiking boots alive for years with some welt dressing and this stuff. Joe Midland, Texas

I'd like to buy my dad a comfortable bike for exercise and recreation. He doesn't like to be hunched over a bike because he has a temperental back. He also needs a comfortable seat. Is there anything for $800 or less? Joe Edison, New Jersey

I have been searching online for the past few hours for piece of equipment that I believe I saw in some gear magazine (the mail order kind). I will describe it: digital watch, with a compass, stopwatch, etc., and a lighter, signal mirror, and small knife blade with various other attachments. It hung from a lanyard and cost around $100.00 or so. Can you help me find a name for this product or where I might be able to order one? Thanks for the help. Bradford Hammar Charleston, West Virginia

For the second year in a row, we have just returned from our annual spring camping trip in southern Utah, and because of blowing dust, the zippers on the tent are EXTREMELY difficult to operate. Are there any methods for treating "dust-laden" zippers in the field? Also, now that we're back, we've washed the tents, sprayed silicon on the zippers—they're better, but still not like they used to be. Any suggestions? I've been told to buy some "zipper wax" to carry camping next time, but no one here seems to carry it. Thanks! Kirk Astroth Belgrade, Montana

I have a 2001 Honda Civic coupe and will be making a cross-country trip. I looking into a cargo rack to outfit my Civic but I'm not sure how much to spend and which brand to go with (Thule, Yakima, or Saris.) The rack will probably only be used for a rooftop storage bag. If you could suggest a rack model I would greatly appreciate your help. Pete Lptey Fairfax, Virginia

I just returned from Mount Rainier with a rope I had bought specifically for this trip but with the intention of using it for rock climbing. I hate to think of the number of times I saw it go under foot. None of my ropemates put a crampon into it, but I sure don't see myself taking a lead fall with it now, especially 100 feet up. But what about glacier travel? Certainly the guides on Rainier leading newbie mountaineers don't replace their ropes after every trip. Is there anything I can do to physically check the condition of my rope and feel comfortable using it for glacier travel? I truly hate to toss a rope after one trip.

I'm really getting into ultralight backpacking, and I hope to do a through-hike of the AT or PCT in the next few years. I do all of my backpacking in the summer, but my Marmot sleeping bag is too heavy (and warm). What choices are there for a light, compressible bag costing less than $100? If there are no bags in this range, would you recommend removing some of the down from my Marmot bag to make it lighter? Tom Bellevue, Washington

Why don't sleeping bag manufacturers make the outer shells on their bags from the se materials used in waterproof-breathable jackets? Thanks for your time and answer. Steve Youngsville, Louisiana

My wife and I like to share a cozy sleeping bag while kayak camping, but we both own "pre-marriage" bags that don't zip together. What we want is one bag wide enough for two, made from synthetic material (since it might get wet), and with a temperature rating of about 20 degrees. Also, as we're both about five-foot-five, it would need to be on the short side. Is our only choice to have a bag custom-made? Andy Kirkland, Washington

What do you recommend for mountaineering in places such as Mount Rainier and Denali as far as headlps and bibs or pants? Would an LED light be better than a regular headlp? I know LED lights last much longer, but what about lighting up the trails? Also, are there any three-layer bibs that you would recommend that are warm, durable, and inexpensive? I like the description of the Marmot Alpinist but it's quite expensive. Are there any less expensive options? Charleton Churchill Pine Grove, California

What are the best winter socks for snow skiing? When I ski, I rent boots and skis, but I find my feet always get cold. What socks should I get to make sure my feet stay warm? Should I use sock liners in addition to high quality wool socks? Brad Chapel Hill, North Carolina

Hailing from sunny California, this is my first year in college in Boston. Here's my situation: New England weather is windy, chilly, and often wet. I need a jacket that will get me through the winter but also look good around town. However, once I buy this jacket, I'll still need money to eat. What can you recommend that won't break the bank, i.e. as close to $100 as possible? Kyle Boston, Massachusetts

Not yet having gone digital, I have a standard 35mm camera with extra lenses, a detachable flash, and the requisite rolls of film and cleaning cloths. So, I'm looking for a backpack-style camera case with plenty separate compartments and padding. Ideally, it'll be sling-style, with small compartments on the front for ease in changing films, lenses, and so forth. I've already checked the local stores and a few large Internet sites, but they seem to make bags only for digital cameras now. Any suggestions? Sarah Tulsa, Oklahoma

For multi-day trips to the Sierras, I've been using an REI Wonderland external-fre pack, 5,000 cubic inches of cavernous, organized, old-school pack. Everybody I see these days, though, has internal-fre packs that look so comfortable (maybe they're fooling me). I still living in the '80s with my Wonderland? Is it time for an internal-fre pack? If so, any suggestions? Alex Chino Hills, California

I planning a two-day, one-night hiking trip along the Appalachian Trail and looking for a gear list. Could you suggest what to pack and a couple of menus (with per person measurements)? The last time I took a trip, my girlfriend and I lugged so much food we could have fed five. Seth New York City

My wife has been using a pair of Asolo AFS Ridge boots for our backpacking trips, typically extended ones through rugged terrain. The Asolos blew out a se in front of the laces and need to be replaced. We are considering the Montrail Moraines or the Asolo 520 GTX boots. Is the Moraine too much boot? Is the Asolo 520 enough boot? Any other suggestions? Louis Oregon City, Oregon

Yes, as an overpronate runner weighing in at 210 pounds, I probably should take up a less impact-prone sport. But I'm still running, so I need some shoes with torsional stability and impact-absorbing capability. For the past year, I have been running in a pair of Brooks Beasts, which have worked pretty well, but not perfectly (Spenco insoles helped some). Can you recommend several running shoes that are suited for a runner of my build? Charles New York City

I'm dumbfounded by all the choices with regard to heart rate monitors. Should I stick with the well-respected Polar or try other brands? Tracy Los Angeles, California

Are there any objective tests comparing the hard- and soft-shell products of different gear manufacturers? Yes, there's a huge ount of marketing hype easily available, but beyond XCR's assertion that it's "25 percent more breathable than standard Gore-Tex," there doesn't seem to be any hard numbers comparing materials. This is surprising when you consider how much consumers are prepared to pay for the latest and greatest. Jeff London, United Kingdom

Last summer, I bought a Shan light touring kayak from Wilderness Systems (based largely on your recommendation, O Great and Wise One). After some great day trips, I'm now planning a multi-night river trip, so I'm looking for some packing advice. The boat has a rear bulkhead and an air bag up front for flotation. Should I pack my gear at the back with extra stuff lashed atop the stern, or can I replace the front flotation bag with a tapered dry bag? Zippo Baltimore, Maryland

Several years ago, I bought a pair of "funny-looking" Salomon Adventure 9 boots. They were virtually perfect, but are finally wearing out. Since there's no sign of a similar boot in today's U.S. Salomon line, can you think of an alternative? Ray Cleveland Heights, Ohio

I'm a letter carrier looking for a quality rain jacket to keep me dry in spring showers or pouring storms, all through the New England seasons. Could you please point me in the right direction? Michael Springfield, Massachusetts

On a recent winter excursion in the Adirondacks, my Whisperlite stove failed. The fuel was pressurizing, but it wasn't reaching the ignition wick due to a blockage in the fuel line. Why does this happen in cold weather (our temperature was in the single digits), and how can it be prevented? John Buffalo, New York

I'm beginning to think that today's trend toward Assos-esque padded cycling shorts—padding formerly being the saddle's job—has left me with more saddle sores. This bulky new style only serves to form a bulk of soggy material once the sweat soaks through, causing blisters and general discomfort. Does anyone make shorts or bibs with either minimal padding or something akin to the original chois style? Between the incontinence of infancy and agedness, I prefer not to wear a diaper while riding. Can you help? Clay Wimberley, Texas

I have been backpacking and hiking for many years but I was recently told that for long hikes I should put on my liners, spread Vaseline on them, and then put on my hiking socks. Do you know anything about this or is this a joke? Joaquin Lira Oshkosh, Wisconsin

I'm going trekking around Mont Blanc and have been told not to drink any glacial meltwater because it contains tiny sharp particles of rock, called talc, which can shred one's insides. I have an Aquira water bottle with a two-micron filter, which is supposed to remove microscopic pathogens. Will it stop talc? Hal Berkeley, California

I've been shopping for a car-camping tent for our family (myself, my husband, two kids aged 14 and nine, plus one growing golden retriever puppy). I want a three-season tent that gives us a fair amount of space, maybe with dividers, but the mind boggles with all the choices: nylon, polyester, taffeta, fiberglass, aluminum, this D mesh, that D mesh. I feel like I need a degree in materials engineering to figure this out! Can you help? Tracey Irvine, California

Sage of swag, I'm in the market for a road bike, and looking for direction. Initially, I'll be using it for fitness riding, but I anticipate riding in local road races in the future. I'm a family man with a limited budget for recreational toys. That said, I want something that's going to stand up—a bike that I won't have to replace or extensively or upgrade as I get into the sport in a bigger way. Is a bike equipped with Shimano 105 group the "minimum" I should be looking at? Which models should I be considering, and at what price point? Greg Basky Saskatoon, Saskatchewan, Canada

I'm planning a through-hike of the Continental Divide Trail this summer, and I want to go ultra-light. What's the best tarp to use—the easiest to set up, the best in wind, and so on? Syd Seattle, Washington

Great burning bush of the gear desert, Marmot Precip hat or urban sombrero? I want to buy a good waterproof hat; hoods are cool and all, but they're sometimes a pain in the fanny pack. I have read that you often prefer hats to hoods. So, would you choose the Marmot Precip Safari Hat, the Outdoor Research Seattle Sombrero, or something different altogether? Please help me before I do something dumb—like ask someone else. Jay Eugene, Oregon

I'm a big guy (six feet five, 270 pounds) who's interested in buying a hybrid bike for some urban biking and trail riding (nothing too extreme or competitive). So I need a bike that fits but doesn't cost a fortune. Also, can you explain mountain- and hybrid-bike sizing conventions, especially as there doesn't seem to be a standard way of measuring hybrid bikes?

As a thrifty person with only occasional needs for real cold weather gear, I'm tempted by the down jacket that Land's End sells for $70. Pretty simple design, 650 fill, seems like something that's pretty tough to screw up. Any experience with how this jacket stands up to some of the pricier down parkas from the more traditional gear makers? I'd be using it for an around the cp and belay over-jacket in the Sierras. Raymond Tarto Oakland, California

I want to buy a bike to ride the two miles to work and head downtown on the weekends, about a 15-mile ride. Thing is, I have an attachment to big comfy handlebars, seats, and three-speed internal gears; I cringe at all the "touring" bikes with their rock-hard seats and hunched-over handlebars. I currently have a cruiser and walk it up hills. Can you recommend a bike that won't break the bank? Tiffany Santa Barbara, California

I bought my first pair of snowshoes, and now I need to buy some snowshoe boots. What do you think of Columbia's Excellerator or Bugabootoo boots? Dan St. Louis, Missouri

Man, do I need some bike advice. I have been riding mountain bikes exclusively for the last ten years. I now want to buy a road bike specifically for commuting and exercise. I would like something fun and comfortable to ride, but geared like a road bike for speed. I considering the Marin Tiburon and the Specialized Sirrus Pro, which are in my price range. What should I go for? Lawrence Elk Grove, California

I know you get lots of questions about the best outdoor cameras, but can you recommend a camera that operates well at high altitudes (above 20,000 feet) and in extremely cold weather (around minus 50). I have heard that autofocus doesn't work above a certain elevation. I'm looking for a compact or SLR that is lightweight, resilient, with easily accessible batteries (for efficiency when changing them in the cold), and which will capture the highest-quality images at the top of the outdoor world. Sarah East Lansing, Michigan

I enjoy everything about my new digital camera except for the short battery life, which is especially annoying when on multi-day hikes when the battery might suddenly go dead. Are there any solar-powered products out there for recharging batteries while on the trail? John Swanton, Maryland

Oh Being of All Gear Wisdom, Following your sage advice, I've been looking for a Yashica T4 point-and-shoot to replace my partner's camera, which bit the Grand Canyon's dust on our last trip there. It appears that Yashica no longer makes the T4. Nor do they seem to have a successor model. What's your current recommendation for either a fixed or zoom lens 35mm P&S? Being a photographic troglodyte, no digital cameras allowed. Rob Brading Fairview, Oregon

I want to take my video camera with me on a trip to the Colorado mountains and hoping I can buy a solar panel to charge the battery. There seems to be some difficulty with finding info. It's a 6-volt battery and I have the adapter that plugs into a car cigarette lighter. Can I buy a 5-watt solar panel that is advertised to charge a 12-volt car battery and use it? Can I just wire up the cigarette lighter receptor to the panel, and then plug the adapter into it? Seems to me that ought to work. But, we don't know much about solar panels other than expeditions use them to charge batteries. Jeannette Singleton

I have never spent a night on the trail, sticking to day trips instead. However, it's something that I think I would like to get into. My hiking partner has the tent, stove, and first aid kit. I don't want to go out and buy all the other equipment (sleeping bag, pad, boots, etc.) until I certain that backcountry camping is for me. What would you suggest for my first trip? . Melissa Greenwood, Delaware

Can you recommend a three-season tent that is well configured and roomy for two people and a dog? Tom Miller San Francisco, California

I in urgent need of a warm sleeping bag for use on an upcoming desert running race I entered in, the Marathon des Sables in Morocco. Although this conjures up visions of heat and sleeping under wispy silk fabric whilst warm winds blow, the reality is that at night, temperatures can plummet to freezing. I'm not too concerned about cost and need a bag which is at least good for about 32 degrees, and most importantly, LIGHT!! It has to be carried and raced with for over seven days. Please recommend waterproof varieties or appropriate techniques as it can pour. Dio Wong Hong Kong, China

My summer bag is an Integral Designs Andromeda Strain (40-degree, Primaloft); my three-season sack is the North Face Cat's Meow (20-degree, Polarguard Delta). Both are sweet bags. My question: can these bags be combined (summer bag inside three-season bag) to make a winter bag? Will I gain much, or will the inside bag be unable to loft up and therefore not provide much additional benefit? Thanks! Bill Stell Charlottesville, Virginia

I was thinking about combining my expandable Mountain Hardwear Galaxy SL sleeping bag with the maker's 40-degree Down Upgrade bag. What do you think about combining these two sleeping bags for a Denali summit attempt? Rob Boston, Massachusetts

A friend and I are planning an attempt to summit Mount Shasta this summer. Neither of us owns an ice ax or crampons and we plan to rent those items when we get to the area. But recently I've been looking at Kahtoolas, which are kind of "crampons light." They're aluminum with no front points and touted as compatible with everything from hiking boots to running shoes. Looks like they might be adequate for a trek up Mount Shasta. Also, I might get some use out of these in future winter hikes. But they are north of 100 bucks (in the same territory as some entry-level crampons). Do you have any experience/insights on Kahtoolas? Mitch Thompson Shaker Heights, Ohio

I want to buy some new cross-country skis that I can use for both touring and downhill, maybe something along the lines of the Karhu Catounts. While these seem to work well for touring on ungroomed trails, would these also suit for telemarking on blue-square trails? Rusty Cresco, Pennsylvania

Can you recommend a good cross-country skiing package that's suitable for both groomed trails and backcountry use? John Duluth, Minnesota

I looking for an internal fre pack that will handle solo weekends, and group week-long outings, but most importantly, comfortably fit my petite (105-pound), feminine fre without breaking the bank. What do you suggest? y Walsh Tallahassee, Florida

Recently a couple friends and I attempted a 14-mile backpacking trip alongside a Class II-III river, with 90 percent of our time spent boulder-hopping, the remaining 10 percent waterborne. Unfortunately, we only managed to go three miles before the small recreational rafts we had to transport our packs got ripped up by the rocks and all the bushwhacking. In light of this, do you know of any companies who sell floating backpacks? Or is there some kind of easy-to-pack inflatable for transporting gear through water. We'd like to complete the se trek next year, but need a better way to float our backpacks. Travis Roseville, California

I'm looking for a recommendation for hydration packs as Christmas gifts for my brother and his girlfriend. They live in the Bay Area and do a lot of outdoor activities such as trail biking, hiking, and climbing. Would you recommend the se model for each of them, or different ones? Verna Washington, DC

I have a bit of a problem. I must have put my pack away a little wet after a spring backcountry ski trip and now all the waterproof coating is coming off the inside of the pack. I have a siliconized nylon pack cover that I will probably use for an upcoming Sierra trip and sprayed the outside of the pack with Nikwax. I also always use a garbage bag inside of the pack to protect my gear. Do you think the pack is done and I need to bite the bullet and buy another? Or do you have any suggestions of ways to fix it? Tim Newport Beach, California

I'm hiking the Grand Canyon rim to rim this spring, and I'm wondering what footwear to use. I like the lightness and cushioning of the trail runners that I've been using for my ten-mile training hikes, but I'm wondering if I need something a little more burly for my unsteady legs over the course of the 24-mile hike. Any thoughts on the Lowa Tempest? Jay Phoenix, Arizona

What's the best way to clean my hands in the wilderness prior to handling contact lenses? My waterless hand sanitizer warns against eye contact and I don't want to use stream water.

My daughter is flying to Europe this fall and is looking for a good all-around pack for all travel essentials, plus a computer. She is small-fred, five-feet four-inches tall, and weighs 110 pounds. This is the only luggage she is taking and she plans on being there five months. The packs needs to be durable and easy to carry. What should she be looking for? Janet Boise, Idaho

I know it's only August, but I have recently taken up running and looking ahead to the looming Ottawa winter. In preparing to outfit myself, I have been doing some reading about soft-shell jackets. The claim seems to be that I won't need to do the usual layering job with one of these—the soft shell can do it all. Is this right? Would a soft shell be the answer to a big part of my winter running wardrobe? Eric Ottawa, Ontario

I'm interested in buying a new kayak for touring and open-water paddling, but one that could also take a little whitewater action once in a while. What would you recommend? Jeff Midland, Michigan

I need a good solo tent in the $200 price range for winter mountain climbing trips. It seems that manufacturers have come out with many new solo tents, but I can't tell if any of them would work for winter camping. Mike Rapid City, South Dakota

In southern California the sun is out and the hills are green. Yes, it's almost spring, the time when a young man's fancy turns to...cycling. My helmet is several years old, and I think it's time to retire it. Thumbing through a number of catalogs, I can't believe the wide range of prices. Just what the heck does $200 buy me that $40 doesn't? Larry Long Beach, California

This summer I plan on taking a backpacking trip to the Selway River or Kelly Creek in Idaho. I hope to do some fishing as well, which will require wading in the river. I do not want to take wading boots due to the weight. Do you have any recommendations for sandals or other footwear that can serve as both hiking sandals and water sandals? I need good sole support for hiking and walking over boulders while wading. I also require a non-slip surface that will grip wet rocks. I have found that hook-and-loops material does not work well when wet. Last summer, the hook-and-loop straps kept coming undone on my Tevas. Any help is greatly appreciated. J.L. Walker

I'm looking for a women's pair of insulated, waterproof or Gore-Tex, crampon-compatible hiking boots. I'm not climbing Mount Everest—what I'm looking for is a boot to get me through the winter when I don't need snowshoes, but it's freezing out and I may need crampons. (Specifically, in the High Peaks area of New York.) I'll be using them for long hikes on paths and over rocks. I don't seem to be able to find the perfect combo as most options seem to be heavy-duty mountaineering types. BJ Guilderland, New York

For a few years I have been using a Macpac Microlight tent, perfect for me and my pack. However, I'm now looking for a slightly larger tent to also accommodate my dog. Finding that Macpacs are not sold in this country and mail order prices are exorbitant, I was wondering what you'd recommend that's comparable in durability, waterproofness, weight, and quality, hopefully for a more reasonable price. Jennifer Seattle, Washington

I live in the city and looking for a bike that I can ride to my local bike trail via city streets (approximately three miles). The trail is dirt and gravel, but I'll also need front suspension because of reckless drivers who sometimes force you onto a sidewalk. I have been to several bike stores and really confused by all the options: Raleigh C500, Cannondale, Giant Cypress LX, Trek? One store advised me to wait until mid-August for the 2004 models to arrive in stores. My budget is $500 to $600. Chris Philadelphia, Pennsylvania

I'm planning to climb Aconcagua next year followed by Denali the year after, and I was wondering about layering for warmth using down sleeping bags and parkas. I want to avoid buying really specialized gear (like the Feathered Friends Rock & Ice Parka, or their Snowy Owl bag) that I can only use on the coldest peaks like Denali. Is it possible to achieve a comfortable temperature rating on this mountain using a combination of the Icefall Parka and the Widgeon bag? The reason I'm asking is I would like one bag for all my mountaineering endeavors (including the not-so-cold trainer mountains). John Toronto, Ontario

I wear prescription lenses in my sunglasses and want to get a similar custom-made pair of glasses for paddling at night. I've heard that a yellow tint on the lenses helps to bring out objects. Is this true? Is there anything else I should consider when ordering this pair of glasses? Dennis Milton, Florida

I'm going to Alaska's Denali in June, so are there any particular jackets out there that you would recommend? Would the Marmot Parbat Parka be sufficient on a breezy day atop Mount Denali? Eric Maryland

How do you know when it's time to replace your running shoes? I have been road running on a pair of New Balance 804s for about a year. I weigh 200 pounds and run about two to three miles five days a week. Any suggestions for new shoes? Craig Portland, Oregon

My son and I need to purchase raingear for an eight-day canoe trek to Minnesota's Boundary Waters Canoe Area this July. Do I need to get a Gore-Tex parka like most people recommend, or are the newer, lighter styles like Marmot's PreCip enough for such a trip? David Wichita, Kansas

A friend suggested that I extend the life of my leather hiking boots by proactively applying se-grip to the stitching and the area where the upper meets the sole of the boot. Is this legitimate advice or have the petroleum distillates simply gone to his head? Chuck Freeport, Maine

I sweat a ridiculous ount and have no problem staying warm, having nordic skied in sub-zero temps wearing only a thin nylon T-shirt and XCR shell. So, I'm in search of the ideal base layer shirt. I like Patagonia's lightweight Capilene, but I'm still experimenting with various fabrics and manufacturers. I'm skeptical of Patagonia's silkweights as the stitching across the shoulders looks like it would be irritating with a big pack on. Do you have any wisdom to impart? Seyil Toronto, Ontario

Can you help me choose a boot for a trip to Argentina's Mount Aconcagua? I have summited several fourteeners in my La Sportiva Makalus without a hiccup, but I'm afraid Aconcagua is too much mountain for these boots. We plan on tackling the Polish Glacier route, and I was leaning towards a plastic double boot like Koflach or Scarpa. But, as usual, your input could sway me! Eric Palmetto, Georgia

I know nylon fabrics deteriorate from too much exposure to the sun, but does nylon lose its strength from old age? Is a sleeping bag that has been in storage for 20 years without seeing one ray of sunshine still "as good as new"? Are there both "good" and "bad" quality nylon fabrics, or are they all made equal? David Sparta, Michigan

OK, so jogging on the trail with a baby isn't safe. But, I would like to go backpacking after our baby is born. Are there any all-terrain strollers suitable for trails? I know there are baby carriers to wear, but dad still has to carry the rest of the gear, doesn't he? M. Dittman Cleveland, Tennessee

Will a space blanket attract lightning? Jeff Santa Monica, California

Now that hikers are supposed to filter/purify all the water they consume, I'm curious if ANY contact with untreated wilderness water is safe? Is it OK to splash water from a clear stre on my face and arms to cool off? Is it OK to jump in a clear lake for a swim? Would doing these things expose me to infection through ears, eyes, nose, ETC.? What about canoeists and kayakers who are in and around untreated water all the time? Mark Her Fullerton, California

My wife says that my regular reading of your column has cost us a fortune but I swear you've saved me money. Here's a chance to prove your worth, and much more importantly, prove me right. It's spring again, and my Mountain Hardwear Guide pants are suffering from a severe case of "glissade bottom." Are they totaled, or is there a way to economically repair this malady without tossing these wonderful but expensive pants in the trash heap? Secondly, I've tried to prevent "g.b." by pulling a pair of shorts over the pants, but to no avail. The shorts just ride up in to full wedgie mode, leaving me uncomfortable, and the pants largely exposed to the worst effects of snow abrasion. Is there some other method to avoid this in the first place, or should I just buy cheap pants for mountaineering? John Giles Carlsbad, California

Airlines have regulations prohibiting travel with fuel bottles and stoves, even if they're empty and purged. How can you fly to backpacking destinations with white gas stoves and fuel bottles? Do the rules make such equipment obsolete for travel where flights are involved? Fun Walled Lake, Michigan

I guessing that the tool that Bradford Hmar was looking for in a recent question is the Schrade I-Quip (http://www.schradeknives.com). It has an altimeter, barometer, digital compass, watch, whistle, mirror, flashlight, lighter compartment, screwdriver, knife, corkscrew, saw, and scissors. Jason Grech Decatur, Georgia

Any recommendations for a two-person backpacking tent big enough for a six-foot, five-inch, 250-pound camper? I already have a Sierra Designs Clip Flashlight two and it seems a bit small for just one person (me), especially after more than two nights of foul weather. Jim McGowan Charlotte, North Carolina
